Elevated water temperature in combination with an increase in daylength stimulate a synchronized onset of spermatogenesis in male Atlantic salmon (Salmo salar, L.) postsmolts [PDF]
Male postsmolt maturation (“jacking”) is undesired in Atlantic salmon aquaculture due to economic and welfare impacts. Unfortunately, incidence of jacking has increased linked to intensive rearing conditions.

Igf3: a novel player in fish reproduction
AbstractAs in other vertebrates, fish reproduction is tightly controlled by gonadotropin signaling. One of the most perplexing aspects of gonadotropin action on germ cell biology is the restricted expression of gonadotropin receptors in somatic cells of the gonads.

Fsh Stimulates Spermatogonial Proliferation and Differentiation in Zebrafish via Igf3 [PDF]
Growth factors modulate germ line stem cell self-renewal and differentiation behavior. We investigate the effects of Igf3, a fish-specific member of the igf family. Fsh increased in a steroid-independent manner the number and mitotic index of single type A undifferentiated spermatogonia and of clones of type A differentiating spermatogonia in adult ...

Antagonistic regulation of spermatogonial differentiation in zebrafish (Danio rerio) by Igf3 and Amh [PDF]
Fsh-mediated regulation of zebrafish spermatogenesis includes modulating the expression of testicular growth factors. Here, we study if and how two Sertoli cell-derived Fsh-responsive growth factors, anti-Müllerian hormone (Amh; inhibiting steroidogenesis and germ cell differentiation) and insulin-like growth factor 3 (Igf3; stimulating germ cell ...

Sex blind: bridging the gap between drug exposure and sex-related gene expression in Danio rerio using next-generation sequencing (NGS) data and a literature review to find the missing links in pharmaceutical and environmental toxicology studies [PDF]
The sex of both humans and Danio rerio has previously been shown to affect the way individuals respond to drug exposure. Genes which allow identification of sex in juvenile zebrafish show potential to reveal these confounding variables between sex in ...

Gene expression analyses of GH/IGF axis in triploid crucian carp with growth heterosis [PDF]
Hybridization and polyploid breeding are the main approaches used to obtain new aquaculture varieties. Allotriploid crucian carp (3n) with rapid growth performance was generated by mating red crucian carp (RCC) with allotetraploids (4n).

Igf3 is essential for ovary differentiation in zebrafish†
AbstractZebrafish gonadal sexual differentiation is an important but poorly understood subject. Previously, we have identified a novel insulin-like growth factor (Igf) named insulin-like growth factor 3 (Igf3) in teleosts. The importance of Igf3 in oocyte maturation and ovulation has been recently demonstrated by us in zebrafish. In this study, we have

Genetic Mapping of Head Size Related Traits in Common Carp (Cyprinus carpio) [PDF]
Head size is important economic trait for many aquaculture fish which is directly linked to their carcass yield. The genetic basis of head size trait remains unclear in many widely cultured fish species.
